MECHANISM FOR CLEANING BO OTOR SHOE UPPERS.

SPECIFICATION forming part of Letters Patent No, 368,105, dated August9, 1887.

Application filed Februmy 17, 1887. Serial No. 228,129. (No model.)

To all whom it may concern:

Be it known that we, LEVI B. N EWHALLan FRANK B. NEWHALL, of Lynn, inthe county of Essex and Commonwealth of Massachusetts, have inventedcertain Improvements in Machines for Cleaning Boot or Shoe Uppers, ofwhich the following, taken in connection with the accompanying drawings,is a specification.

This invention relates to mechanism for cleaning boot or shoe uppers,and the nature thereof is 'fully described and specifically claimedhereinafter.

Referring to the drawings, which accompany and form a part of thisspecification, Figure l is a plan view of a machine made in accordancewith and embodying this invention. Fig. 2 is a side elevation of saidmachine, made partly in section to illustrate details of construction;

Figs. 3, 4, 5, 6 are details to be referred to hereinafter.

The driving-shaft A is mounted in and al-v lowed to be revolved in theframeB B, and on the shaft is a sheath, D,to receive the drivingcordfrom any suitable driving pulley. The frameB B hasits endsjournaled inthe supporting-frame E, as shown inFig. 2. Projecting outwardly from therear end of shaft A is an eccentric-pin,F,that enters a suitable hole inthe block H, and the block H is arranged to permit verticalmovementinitssupporting standard K, and from this construction theshaftA is given a compound movement. The pin F being eccentric with theshaft A,it follows that when the shaft is revolved either the pin musttravel round the center of the shaft or the shaft must travel round thecenter of the pin, and taking advantage of this, we allow the pin totravel round the shaft during part of the revo lution, when it lifts anddepresses the block H, as indicated in Figs. 3 and 5, to which end theblock H permits the necessary vertical move mentiu standard K. Duringthe other portions of the revolution the shaft must travel roundthe'pin, and this imparts a lateral vibratory motion to the shaft, asindicated by Figs. 4 and 6, and to permit this the frame B has its endssuitably pivoted in standard E, as shown.

The cleaning-pad is mounted on the forward end of said shaft A. To thisend we provide the core a with a central longitudinal bore to receivethe shaft A, as indicated in Fig. 2.

is surrounded by a piece of thick felt, I).

This core is preferably composed of wood, and This felt projects ateither end beyond the core, and recesses are thus formed in whichholding and'adjusting devices are positioned, which will hereinafter bedescribed. At the end is a re-enforciug sleeve or thimble, w, composedof rubber or similar material. It gives a supporting but yieldingquality to the pad at this point, and so prevents the pad from beingjammed out of shape. It further serves to shield the end of the shaftand its incident clamps, and so prevents the shoe from being injured ifaccidentally or otherwise pressed against the end of the pad.

The pad is covered by a piece of plain cotton cloth, (I; but we areaware that chamoisskin or other textile fabrics would give good results,though not so economical. To facilitate the adjusting of the fabric ontothe pad, and to insure its remaining there, we employ the metallicferrules e f, which are secured to the core aand are threaded suitablyto receive the nuts h k, as'shown in Fig. 2. .The ferrule e is furtherprovided with an inside thread to engage a thread on the outside ofshaft A, and so retain the pad on said shaft while in operation. Inadjusting the fabricit is first wrapped about the felt. The edges at oneend are put into clamp m and the nut 0 turned up, as in Fig. 2. Theedges of the opposite end are put into clamp n, and thereupon the nut his moved inward, forcing forward the clamp n, and so stretching thefabric tightly over the pad. It may be further tightened by a similarmovement of the clamp it, whenever by use or otherwise it gets loosened.

In operation the upper is held in the hands of the workman and pressedupward under the pad. We are aware that the revolving or the vibratingmovement ofthe pad may be dis-.

pensed with; but the pad will not last so long,

and will consequently not be so economical as when the compound movementis employed.

WVe claim-- 1. The combination of the core a, the felt I) 2. Inacleaningpad for boots or shoes, and in combination the core a, the feltI), the fabric (1, covering the said felt, the holding devices,substantially as described, for one end of said 5 fabric, and theholding and adjustable devices, as the clamp n and screw 71,substantially as de scribed.

3. In combination, the pad, the fabric (Z, and the clamps m and a, andscrews h 7c,for holding 10 and adjusting the said fabric to the pad,substantially as described.

4. In combination, the core a, the felt I), snrrounding said core andprojecting at the ends beyond the core,whereby recesses are formed,

1 the fabric covering the felt, and the holding devices for said fabricsituated within the recesses at the ends of the felt-covering,substantially as described.

5. In combination, the shaft, the core a, sur- 20 rounding the same andcarried thereby, the cleaning material extending peripherally about thecore, and the sleeve or thimble of rubber situated on the end of saidcore and extending beyond the end of the shaf t,substantiall y as de- 25scribed.

6. In combination, the core a, the yielding cleaning material projectingbeyond the said core, and the rubber piece 10 at the end of said coreengaging with the projecting cleaning maoted frame B B, means forrevolving the shafb 4 5 and the mechanism described for giving to theshaft a lateral reciprocating movement, substantially as described.

10. The combination ofthe core a,eo|nposed of wood or other suitablematerial, as set forth, the felt b,and the outer covering of textilefabric, the sleeve w, and means for securing the fabric to the pad,substantially as described.
